Application filed January 2, 1906. Serial No. 294,326,

To all whom, it may concern:

Be it known that I, AnoLF WILI-IELM KUT- ZER, a subject of the Emperor of Austria- Hungary, residing at Hauptstrasse, Stiinz, near Leipsic, Germany, have invented certain newand useful Improvements in Hope- Grips for Suspended B0 c Railways; and I do hereby declare the fo lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a rope-grip for suspended rope railways wherein a haulingrope is clamped between gripping-jaws actuated by the weight of the vehicle and its load, and comprises a traveling frame and rollers, a

rope-clamp supported on the frame, rocking shafts passing through the axles on which the rollers are mounted, arms fixed on the shafts at opposite sides of the rollers, a load-hanger suspended from the free ends of a pair of arms on one side of the frame, and gripping-jaws connected with a pair of arms on the other side of the frame.

The advantage of the present rope-grip over others of a similar kind consists in the load being suspended from a point midway of the length of the traveling frame and the strain on the grip being unaltered, or only inappreciably so, when the truck moves along an incline. Moreover, all movable parts are easily accessible, so that any damage can be repaired at once from outside.

In the accompanying drawings, Figure 1 is a side elevation of the traveling frame or trolley; Fig. 2, a similar view to Fig. 1 of the oposite side, and Fig. 3 a transverse section.

The load-hanger a is suspended from the slaft I) and cross-head d, connected with the levers by means of the slots g and bolts h.

In the form of the invention illustrated by way of example the shafts m, with which the levers 7c are connected, are carried through the axles of the wheels n. At the opposite ends of the shafts 'm are short levers 7c, which are connected with one another by a crosshead d Fig. 2, bolts h, and slots g after the same manner as the levers k. The crosshead (1 is guided on the lug p of the traveling frame by a pin 0. The two grip ing-jaws q are pivoted at 1" on brackets on t e framing, and arms q on the aws are connected with the cross-head d by means of the rods t. Thus through the Weight of the load-hanger and load the cross-head d, Fig. 1, is pulled down and therewith also the levers k k which pull down the cross-head d. The grippingjaws q (1 move correspondingly around their pivots r and clamp the trolley firmly to thetraction-rope s. The invention may, however, be so carried out that only one grippingjaw is movable,while the other is fixed; but, having regard to the gripping stroke or action, it is desirable that both jaws should be movable. According to the proportional lengths of the levers 7c is the clamping pressure may be made greater or less. If the ends of the levers 7c 76 be provided with toothed segments, the cross-heads d d will not be required.

The space, Fig. 3, left in the central part of the traveling frame may be advantageously employed for receiving-a lubricating device by means of which the traveling rope may be furnished with the requisite lubricating material. For the purpose of releasing the trolley the shaft 1) is provided with a roller a, which runs in the usual manner on a track inside the station, and thereby causes the levers 7r to swing up,'and thus effects the opening of the grip q.

What I claim, and desire to secure by Letters Patent, is-

1. In a ropegrip for suspended rope railways, the combination with a traveling frame and rollers and a rope-clamp supported thereby, of rocking shafts, arms on the shafts adapted to operate the rope clamp, and means for actuating the shafts to which the load is directly connected.

2. In a rope-grip for suspended rope railways the combination with a traveling frame and rollers and a rope-clamp supported thereby, of rocking shafts, two opposite pairs of arms on the shafts, a cross-head arranged to connect one pair of opposite arms, means for connecting said crosshead to the gripping jaws, and a cross-head connected with the other pair of arms and from which the load is directly suspended.

3. In a rope-grip for suspended rope railways the combination with a traveling frame I and rollers and a rope-clamp supported thereby, of rocking shafts, two opposite pairs of arms on the shafts, a cross-head arranged to connect one pair of opposite arms, means for connecting said cross-head to the grippingjaws and a cross-head connected with the other pair of arms, a hanger to which the load is attached, and a direct connection between the hanger and the last-named cross-head.

4. In a rope-grip for suspended rope railways the combination with a traveling frame and rollers and a rope-clamp supported thereby, of rockin shafts, tWo opposite pairs of arms on the s afts, a cross-head arranged to connect one pair of opposite arms, a gulde on the frame for said cross-head, means for connecting said cross-head to the gri ping-jaws, and a cross-head connected wit the other pair of arms and from Which the load is directly suspended.

5. In av rope-grip for suspended rope rail Ways the combination with a traveling frame and rollers and a rope-clamp supported thereby, of rocking shafts, two opposite pairs of ADOLF WILHELM KUTZER.

Witnesses HERM TAcK, RUDOLPH FRICKER.

It is hereby certified that the name of the patentee in Letters Patent No. 821,174,

granted May 22, 1906, for an improvement in Rope-Grips for Suspended Rope Railways, was erroneously written and printed Adolf Wilhelm Kiitzer, whereas said name should have been written and printed Adolf Wilhelm Kutzer, and the names of the witnesses should be Harm. Sack and Rudolph Frz'cke instead of Herm. Tack and Rudolph Fricker; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Oflice.

Signed and sealed this 24th day of July, A. D., 1906.
